Embodiment Construction

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0014] The classification of agricultural land is a comprehensive assessment of the quality of agricultural land in three aspects: natural, social and economic. In different regions, the factors affecting the quality of agricultural land are often different, and even the same factor has different degrees of influence on the quality of agricultural land in different regi...

Abstract

The embodiment of the invention provides a method and a device for dividing an index area of agricultural land grading factors. The method comprises the following steps: taking all index data of eachindex area to be divided as an input vector, inputting a self-organizing mapping neural network model, and outputting a result of a first clustering analysis; adopting an AP clustering algorithm to perform a second clustering analysis on the result of the first clustering analysis, and according to the result obtained by the second clustering analysis, determining the partition result of the indexarea to be partitioned. Through adoption of clustering analysis, the subjective influence of human experience is avoided. In addition, the quadratic clustering analysis combined with a self-organizing map neural network and AP clustering is used to obtain more accurate clustering results, so the method and the device are practical.

Description

technical field [0001] The invention relates to the field of agricultural land quality assessment, in particular to a method and device for dividing agricultural land grading factor index areas. Background technique [0002] Agricultural land is the basis of grain production, and reasonable planning and use of agricultural land is the prerequisite for ensuring grain production. In order to scientifically quantify the quality of agricultural land and make rational use of it, it is necessary to classify agricultural land. The grading of agricultural land is a process of comprehensively evaluating the quality of agricultural land based on its natural, social, and economic attributes, and then classifying it into different grades. In the process of agricultural land grading, the scientific division of grading factor index areas is the basis and premise for the true and accurate grading results. [0003] The grading factor index area refers to the area where the grading factor ...
